FAQ
Does this store my birthday?
No. The age math runs locally in your browser for this page experience.
Why might my age differ from another calculator?
Different tools may round months or days slightly differently at edges of the month. For legal or official age, always follow your jurisdiction’s rules.
Can I use this for someone else’s birthday?
Yes — pick any date you are allowed to use. Do not enter sensitive data you are not permitted to process.
